I have thought about that, bro. Earlier i bought couple of 11W UVC bulbs and transformers to them, planned to make air purifier with them. But now i'm thinking about using one of them in grow, just for very short period of time once a day or smth. That would surely freak plant out. Maybe some day in bigger box, will see. Now already i have microwave oven here, no point of adding anything here already, effect could be very negative even...
